Answer:
X=9
Step-by-step explanation:
We want to first understand that a triangle will always be 180°. Next, we want to look at both where 25° and 12x-3 are. If we look closely we can see that they are the vertical angles of the interior angles of the triangle. To solve this algebraically we have to basically add all the angles (including 12x-3) to solve for x.
Adding all the angles together would look like this: 25+50+12x-3. Next, add up all like terms to get 12x+72=180. You want to get x by itself by subtracting by 72 on both sides to get 12x=108. Isolate x by dividing by 12 on each side which results in x=9

Answers
Given:
The population of continent of South America in 2010 is 395, 280, 204.
To find:
The closest estimate of this number.
Solution:
We have,
[tex]Population = 395, 280, 204[/tex]
The approximate value of this number is
[tex]Population \approx 400, 000, 000[/tex]
The scientific form of this value is
[tex]Population = 4\times 10^8[/tex]
Therefore, the correct option is C.

Answers
Answer:
[tex]\sqrt{\frac{9}{2} }[/tex]
Step-by-step explanation:
Given dimensions:
The right angle system is a 45 - 45 - 90
Hypotenuse = 3cm
Unknown:
Adjacent and opposite sides = ?
Solution:
In this triangle, the adjacent and opposite sides are equal to one another. So,
Let adjacent = y
opposite = y
For right angle triangles as this, using the Pythagoras theorem,
hypotenuse² = adjacent² + opposite²
Insert the parameters and solve;
3² = y² + y²
2y² = 9
y² = [tex]\frac{9}{2}[/tex]
y = [tex]\sqrt{\frac{9}{2} }[/tex]

Simon and his niece marcie are comparing their ages to see if there is a mathematical connection. They find that Simon is three years more than four times marcie' age. The sum of their ages is 58. Let m be marcie's age. Could marcie be seven years old? Write an expression for Simon's age in terms of the variable m. Write and equation that models the information given Now solve for m? What is marcie's age? What is Simon's age?
Answers
Answer:
The expression for Simon's age in terms of the variable m would indicate that Simon's age is equal to four times Marcie's age plus 3:
s=4m+3 (1)
Also, you know that the sum of their ages is 58, which is:
s+m=58 (2)
You can replace (1) in (2) and solve for m to find Marcie's age:
4m+3+m=58
5m=58-3
5m=55
m=55/5
m=11
Finally, you can replace m in (1) to find Simon's age:
s=4(11)+3
s=44+3
s=47
According to this, Marcie is 11 years old and Simon is 47 years old.
